Is 1.d4 c3 good?
d4 is the better opning move as there is two ways to win by force in it, while 1. e4 only has one. 1. e4 is best for beginners, since it leads to alot of diffrent pawn structures, and logical play.

d4 sux... I've thought of aborting every game that starts that way

1. d4 is a very good opening move. 1. ... c6 isn't such a great response by black.
2. c3 is not a very good second move for white, regardless of black's first move.
So whichever question you were asking, there's your answer!
In 1.d4 c6(I meant c6 not c3) 2. c4 d5, it becomes very similar to caro-kann which I already learned

There are a few reasons why playing 1...c3 against 1.e4 and 1.d4 might have some disadvantages:
1. Limited transpositional opportunities: 1...c3 can lead to some specific openings, such as the Alapin Sicilian or the Elephant Gambit, but it doesn't offer many opportunities to transpose into other openings. This can make it harder to vary your repertoire and keep your opponents guessing.
2. Limited control of the center: In the openings that 1...c3 leads to, Black often gives up control of the central squares, which can make it more difficult to develop their pieces and create a solid position.
3. Weaknesses on the queenside: By advancing the c-pawn, Black often creates a weakness on the queenside that White can try to exploit. This can make it harder for Black to hold their position and create counterplay.
4. Reduced flexibility: 1...c3 can be a somewhat inflexible move, as it commits Black to a specific plan and limits their options. This can make it harder for Black to adapt to different situations and respond to their opponent's plans.
While not a terrible move, it does carry with it some significant disadvantages, which, would be worthy of either studying or avoiding altogether by finding a different move.

c7 pawn can't go four squares ,its not a rook.
Sure it can - it will just take you 3 turns to do it!

Did you shoot up the whiskey before posting this? Sheesh!
It is 1...c6, not 1...c3.
How on earth do you get the Alapin (1 e4 c5 2.c3) or the Elephant Gambit (1.e4 e5 2.Nf3 d5) out of 1...c6?
And it does not reduce flexibility compared to any other move against 1.d4.
1...d5 - Committal and weakens the a3-f8 and h2-b8 diagonals for Black, but controls e4 and c4 and gains space.
1...e6 - Also committing to a light square defenses
1...Nf6 - Blocking Black from any ...f5 systems
No move is completely non-committal.
